How to resize a class in a class diagram in visio 2007?

[Kun Niu]

Dear all,
I wonder if someone here happens to have the same problem with me.
I've just finished a UML class diagram with visio 2007.
I have a function with many parameters. So the box containing the class
becomes too long.
If I change the box to suitable width, the letters in other function come
out of the class box.
But I find that I can't change the height of the class box.
Would anyone here give me some hints how to change the height of a class box?
Thanks in advance for any suggestion.

Actually this behavior is by design, you could get into the shapesheet or
remove the protection for the different groups in the shape but it is not a
good idea. These shapes are designed to interact with other components in
this solution.

Hi, thank you for your reply.
Would you mind telling me how to get into the shapesheet or remove the
protection?
I find that I can only change the width of the class diagram.
But I can't change the height of the diagram.
Do you mean that I should limit the number of parameters in my functions?
Thanks again for your reply.
